![### Groundwater Analysis
Groundwater is characterized by the following chemical analysis:
- \( Ca^{2+} = 80 \, \text{mg/L as} \, Ca^{2+} \)
- \( Mg^{2+} = 55 \, \text{mg/L as} \, Mg^{2+} \)
- \( HCO_{3}^{-} = 350 \, \text{mg/L as} \, CaCO_{3} \)
The pH of the groundwater is 8.0.
### Equivalent Weights
The table below lists the equivalent weights of various species found in the groundwater:
| **FORMULA** | **EQUIVALENT WEIGHT (g/EW)** |
|-------------|-------------------------------|
| \( CaCO_{3} \) | 50 |
| \( Ca^{2+} \) | 20 |
| \( Mg^{2+} \) | 12.2 |
| \( HCO_{3}^{-} \) | 61 |
### Conversion Formula
To convert concentrations to mg/L as \( CaCO_{3} \):
\[ \left( \frac{mg}{L} \, \text{as} \, CaCO_{3} \right) = \left( \frac{mg}{L} \, \text{as species} \right) \times \left( \frac{\text{Equivalent Weight of} \, CaCO_{3} \, \text{(g/EW)}}{\text{Equivalent Weight of Species} \, \text{(g/EW)}} \right) \]
### Explanation of Diagram
The document contains a table displaying formulas and their equivalent weights in grams per equivalent weight (g/EW). It also includes a formula for converting mg/L concentrations of various species to mg/L as \( CaCO_{3} \), using their respective equivalent weights.
This information is crucial for understanding the chemical composition of groundwater and for performing relevant calculations in water chemistry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe0cb8a2a-5df1-4740-b525-1afbd2ddcac5%2F3df99acb-5b66-49df-8d11-4702ada71e58%2F00qezy_processed.jpeg&w=3840&q=75)
